Initial Installation and Start-Up
Be sure you set the hydraulic flow (GPM) to the generator at
Approximately 62.5 HZ or 3750 RPM with NO electrical load
on the generator.
By using this setting you will have approximately 60HZ (cycles) or 3600
RPM when you are running at full rated load.
One way this can be accomplished is by using a Photo Tachometer on
our generator coupling or generator
cooling fan.
A Photo Tachometer is an inexpensive tool that can be purchased at
McMasters, Grainger, Sears or any other electrical supplier.
ADVANTAGES OF USING A FABCO POWER TRI-PHASE GENERATOR
1. MOTORS AND WIRES ARE SMALLER THAN SINGLE PHASE INSTALLATIONS FOR THE SAME HORSE
POWER RATINGS.
2. MOTOR REVERSING ON BOOM AND LADDER TRUCKS WITHOUT USING MULTIPLE
HYDRAULIC LINES. LESS MAINTENANCE AND BREAK DOWNS USING ELECTRIC MOTORS AND
FLEXIBLE CABLES.
3. MATERIALS AND INSTILLATION COSTS ARE MUCH LESS THAN FULLY
HYDRAULICALLY ACTUATED SYSTEMS

Some units may be equipped with integral priority flow control, refer to specific model number.
** External case drain line may be required on some units refer to specific model number.
When external case drain is required it should be unobstructed direct return to reservoir with a minimum I.D. no less
than that of case drain port on generator motor.

3.
Faulty capacitor
Faulty winding
REMEDIES
1. Check RPM and set at nominal
value.
2. Check and replace.
3. Check that winding resistance is
as shown in the tables.
HIGH NO-LOAD VOLTAGE
1. Speed too high.
1. Check and adjust RPM’s
LOW NO-LOAD VOLTAGE
1. Speed too low.
2. Faulty rotary diodes.
3. Breakdown in windings.
1. Check and adjust RPM’s
2. Check and replace.
3. Check winding resistance, as
per tables.
PROPER NO-LOAD BUT LOW
LOADED VOLTAGE
1. Low loaded speed.
2. Load too large.
1. Check and regulate RPM.
2. Check and change.
3. Check and replace.
3.
